CHANGES file includes:
Changes that improve compatibility w/ the Sixth Edition Unix shell
are marked w/ a `C:' in the details below.
-------------------------------------------------------------------------------
[osh-20070324]:
osh.c:
* In main(), changed when fdfree() is called so that it is in a more
ideal sequence with other operations according to how the shell is
invoked (e.g., interactive shell vs. non-interactive shell).
-------------------------------------------------------------------------------
[osh-20070321]:
* Imported the project into a local subversion repository.
* Changed the all of the code to "#include <stdbool.h>" and to use
the "bool" data-type macro where appropriate.
Makefile:
* Added SYSCONFDIR and a new `man' target.
osh.c:
* Defined _PATH_SYSTEM_LOGIN as `SYSCONFDIR/**/"/osh.login"' instead
of "/etc/osh.login" so that the user can use SYSCONFDIR (/etc by
default) at build-time to specify the directory where the shell
shall search for its system-wide initialization file.
* Added a new special parameter, $v, which makes the version of the
osh package available as a read-only string. The format is
`osh-YYYYMMDD' for official releases and `osh-current (YYYYMMDD)'
(interpreted as one word) for development snapshots.
* Fixed a bug where interactive shells were no longer ignoring SIGTERM
when invoked, as they are supposed to. Now, SIGTERM is being ignored
again upon invocation of all interactive shells.
* Fixed the output from doing a `sigign' so that it matches its
documentation in osh.1: "..., a list is printed of those signals
which are ignored by sigign in the current shell."
Previously, the output from a `sigign' could be a little confusing.
Now, its output only indicates those cases where a given signal is
being ignored w/ the possibility that it can then be unignored
(reset) in the current shell context.
if.c:
* Added 3 new primaries: -ef (equal files - same device, same inode),
-nt (newer than), -ot (older than). See the if(1) manual page for
full details.
-------------------------------------------------------------------------------
[osh-20070131]:
osh.1:
* Made a few minimal changes to synchronize the manual w/ the code.
osh.c 1.2 (jneitzel) 2007/01/14:
* Changed the `chdir: No old directory' diagnostic to
`chdir: No previous directory' to match the manual.
-------------------------------------------------------------------------------
[osh-20061230]:
The following files have been removed in this release:
examples/*: These files are now available at:
http://jneitzel.sdf1.org/osh/initialization_files/
tests/*: ... until I have a chance to rewrite them ...
*.1:
* Changed all instances of `UNIX' to `Unix' since the name
of the Unix operating system is not an acronym.
pexec.c:
* Fixed a possible, but very unlikely, memory leak.
osh.c:
C: Rewrote the shell! It is now a combination of the ports of the
original source code from sh6.c and glob6.c (see CHANGES_sh-to-sh6)
w/ the prior enhancements which were found in osh-060124/osh*.[ch] .
fd2.c:
* Removed the call to lseek(2) to end-of-file for errors.
The shell determines when this is necessary.
* Changed the `: no shell' diagnostic to `: No shell!'
in the spirit of sh6(1).
goto.c:
* Fixed a bug which interfered w/ finding a requested label when
its first character had the high-order bit set. The value of the
first character is now passed to getlabel() as an unsigned char
converted to an int to allow correct comparison in such a case.
if.c:
* Removed the call to lseek(2) to end-of-file for errors.
The shell determines when this is necessary.
* Changed the method used to build the argument list for all commands
executed by this utility, and removed the `Too many args' diagnostic.
The maximum length of the argument list for a command is now limited
only by the maximum length that the invoker can pass and by any
system-imposed limit for execve(2) (see E2BIG in errno(2)).
* Changed the `: no shell' diagnostic to `: No shell!'
in the spirit of sh6(1).
* Changed the diagnostic used for `!', `-a', `-o', and `(' operator
errors from `: argument expected' to `: expression expected'.

Fixes PR 35265, although I did not use the patch provided therein.
Based on PR 22994 by Anthony Mallet.
I modify to adapt to recent pkgsrc tree and update from 1.4 to 1.6.
eltclsh (editline tcl shell) is an interactive shell for the TCL
programming language. It provides command line editing, history browsing
as well as variables and command completion thanks to editline
features. The completion engine is programmable in a way similar to tcsh,
and comes with an programmed completion for the whole TCL language by
default.
The package also provides elwish, an interactive interpreter for the Tk
toolkit.
This document details the changes between this version, bash-3.2-release,
and the previous version, bash-3.2-beta.
1. Changes to Bash
a. Fixed a bug that caused the temporary environment passed to a command to
affect the shell's environment under certain circumstances.
b. Fixed a bug in the printf builtin that caused the %q format specifier to
ignore empty string arguments.
c. Improved multibyte character environment detection at configuration time.
d. Fixed a bug in the read builtin that left spurious escape characters in the
input after processing backslashes when assigning to an array variable.
2. Changes to Readline
a. Fixed a redisplay bug that occurred in multibyte-capable locales when the
prompt was one character longer than the screen width.
------------------------------------------------------------------------------
This document details the changes between this version, bash-3.2-beta,
and the previous version, bash-3.2-alpha.
1. Changes to Bash
a. Changed the lexical analyzer to treat locale-specific blank characters as
white space.
b. Fixed a bug in command printing to avoid confusion between redirections and
process substitution.
c. Fixed problems with cross-compiling originating from inherited environment
variables.
d. Added write error reporting to printf builtin.
e. Fixed a bug in the variable expansion code that could cause a core dump in
a multi-byte locale.
f. Fixed a bug that caused substring expansion of a null string to return
incorrect results.
g. BASH_COMMAND now retains its previous value while executing commands as the
result of a trap, as the documentation states.
2. Changes to Readline
a. Fixed a bug with prompt redisplay in a multi-byte locale to avoid redrawing
the prompt and input line multiple times.
b. Fixed history expansion to not be confused by here-string redirection.
c. Readline no longer treats read errors by converting them to newlines, as
it does with EOF. This caused partial lines to be returned from readline().
------------------------------------------------------------------------------
This document details the changes between this version, bash-3.2-alpha,
and the previous version, bash-3.1-release.
1. Changes to Bash
a. Fixed a source bug that caused the minimal configuration to not compile.
b. Fixed memory leaks in error handling for the `read' builtin.
c. Changed the [[ and (( compound commands to set PIPESTATUS with their exit
status.
d. Fixed some parsing problems with compound array assignments.
e. Added additional configuration changes for: NetBSD (incomplete multibyte
character support)
f. Fixed two bugs with local array variable creation when shadowing a variable
of the same name from a previous context.
g. Fixed the `read' builtin to restore the correct set of completion functions
if a timeout occurs.
h. Added code to defer the initialization of HISTSIZE (and its stifling of the
history list) until the history file is loaded, allowing a startup file to
override the default value.
i. Tightened up the arithmetic expression parsing to produce better error
messages when presented with invalid operators.
j. Fixed the cross-compilation support to build the signal list at shell
invocation rather than compile time if cross-compiling.
k. Fixed multibyte support for non-gcc compilers (or compilers that do not
allow automatic array variable sizing based on a non-constant value).
l. Several fixes to the code that manages the list of terminated jobs and
their exit statuses, and the list of active and recently-terminated jobs
to avoid pid aliasing/wraparound and allocation errors.
m. Fixed a problem that allowed scripts to die due to SIGINT while waiting
for children, even when started in the background or otherwise ignoring
SIGINT.
n. Fixed a bug that caused shells invoked as -/bin/bash from not being
recognized as login shells.
o. Fixed a problem that caused shells in the background to give the terminal
to a process group other than the foreground shell process group.
p. Fixed a problem with extracting the `varname' in ${#varname}.
q. Fixed the code that handles SIGQUIT to not exit immediately -- thereby
calling functions that may not be called in a signal handler context --
but set a flag and exit afterward (like SIGINT).
r. Changed the brace expansion code to skip over braces that don't begin a
valid matched brace expansion construct.
s. Fixed `typeset' and `declare' to not require that their shell function
operands to be valid shell identifiers.
t. Changed `test' to use access(2) with a temporary uid/euid swap when testing
file attributes and running setuid, and access(2) in most other cases.
u. Changed completion code to not attempt command name completion on a line
consisting solely of whitespace when no_empty_command_completion is set.
v. The `hash' builtin now prints nothing in posix mode when the hash table is
empty, and prints a message to that effect to stdout instead of stderr
when not in posix mode.
w. Fixed a bug in the extended pattern matching code that caused it to fail to
match periods with certain patterns.
x. Fixed a bug that caused the shell to dump core when performing filename
generation in directories with thousands of files.
y. Returned to the original Bourne shell rules for parsing ``: no recursive
parsing of embedded quoted strings or ${...} constructs.
z. The inheritence of the DEBUG, RETURN, and ERR traps is now dependent only
on the settings of the `functrace' and `errtrace' shell options, rather
than whether or not the shell is in debugging mode.
aa. Fixed a problem with $HOME being converted to ~ in the expansion of
members of the DIRSTACK array.
bb. Fixed a problem with quoted arguments to arithmetic expansions in certain
constructs.
cc. The command word completion code now no longer returns matching directories
while searching $PATH.
dd. Fixed a bug with zero-padding and precision handling in snprintf()
replacement.
ee. Fixed a bug that caused the command substitution code not to take embedded
shell comments into account.
ff. Fixed a bug that caused $((...);(...)) to be misinterpreted as an
arithmetic substitution.
gg. Fixed a bug in the prompt expansion code that inappropriately added a
\001 before a \002 under certain circumstances.
hh. Fixed a bug that caused `unset LANG' to not properly reset the locale
(previous versions would set the locale back to what it was when bash
was started rather than the system's "native" locale).
ii. Fixed a bug that could cause file descriptors > 10 to not be closed even
when closed explicitly by a script.
jj. Fixed a bug that caused single quotes to be stripped from ANSI-C quoting
inside double-quoted command substitutions.
kk. Fixed a bug that could cause core dumps when `return' was executed as the
last element of a pipeline inside a shell function.
ll. Fixed a bug that caused DEBUG trap strings to overwrite commands stored in
the jobs list.
2. Changes to Readline
a. Fixed a problem that caused segmentation faults when using readline in
callback mode and typing consecutive DEL characters on an empty line.
b. Fixed several redisplay problems with multibyte characters, all having to
do with the different code paths and variable meanings between single-byte
and multibyte character redisplay.
c. Fixed a problem with key sequence translation when presented with the
sequence \M-\C-x.
d. Fixed a problem that prevented the `a' command in vi mode from being
undone and redone properly.
e. Fixed a problem that prevented empty inserts in vi mode from being undone
properly.
f. Fixed a problem that caused readline to initialize with an incorrect idea
of whether or not the terminal can autowrap.
g. Fixed output of key bindings (like bash `bind -p') to honor the setting of
convert-meta and use \e where appropriate.
h. Changed the default filename completion function to call the filename
dequoting function if the directory completion hook isn't set. This means
that any directory completion hooks need to dequote the directory name,
since application-specific hooks need to know how the word was quoted,
even if no other changes are made.
i. Fixed a bug with creating the prompt for a non-interactive search string
when there are non-printing characters in the primary prompt.
j. Fixed a bug that caused prompts with invisible characters to be redrawn
multiple times in a multibyte locale.
k. Fixed a bug that could cause the key sequence scanning code to return the
wrong function.
l. Fixed a problem with the callback interface that caused it to fail when
using multi-character keyboard macros.
m. Fixed a bug that could cause a core dump when an edited history entry was
re-executed under certain conditions.
n. Fixed a bug that caused readline to reference freed memory when attmpting
to display a portion of the prompt.
3. New Features in Bash
a. Changed the parameter pattern replacement functions to not anchor the
pattern at the beginning of the string if doing global replacement - that
combination doesn't make any sense.
b. When running in `word expansion only' mode (--wordexp option), inhibit
process substitution.
c. Loadable builtins now work on MacOS X 10.[34].
d. Shells running in posix mode no longer set $HOME, as POSIX requires.
e. The code that checks for binary files being executed as shell scripts now
checks only for NUL rather than any non-printing character.
f. Quoting the string argument to the [[ command's =~ operator now forces
string matching, as with the other pattern-matching operators.
4. New Features in Readline
a. Calling applications can now set the keyboard timeout to 0, allowing
poll-like behavior.
b. The value of SYS_INPUTRC (configurable at compilation time) is now used as
the default last-ditch startup file.
c. The history file reading functions now allow windows-like \r\n line
terminators.
Patch provided by Martin Wilke via PR 34313.
[osh-060124]:
Makefile:
* Added targets for building/installing sh6(1) and glob6(1).
Refer to the README file for further details.
* Removed the `check-sh6' target since the tests were originally
written for osh(1) and sh6(1) as Thompson-shell reimplementations,
not ports.
sh6:
* Changed sh6(1) from being a reimplementation which is compiled from
the same sources as osh(1) to being a port of the original Thompson
shell from Sixth Edition Unix. Refer to the CHANGES_sh-to-sh6 file
for further details.
osh:
C: Treat both `( ; )' and `( & )' as syntax errors.
C: Print the process ID for each command of an asynchronous pipeline,
not just the last command.
C: Added the `newgrp' special command. It is similar to `login'
except that the newgrp(1) utility replaces the current interactive
shell rather than the login(1) utility.
* When opening `/dev/null' is needed for an asynchronous command,
call open(2) w/ the O_RDONLY flag instead of O_RDWR.
From DESCR:
mksh is the MirBSD enhanced version of the Public Domain Korn
shell (pdksh), a bourne-compatible shell which is largely si-
milar to the original AT&T Korn shell. It includes bug fixes
and feature improvements in order to produce a modern, robust
shell good for interactive and especially script use.
New in this release
=====================
** Support for interix
** Ignoring of synchronous signals
The procedures IGNORE-SIGNAL and HANDLE-SIGNAL-DEFAULT have been
added.
** Support for gcc 4.0
** 0.6 for module path
The standard module path now contains
${prefix}/lib/scsh/modules/0.6 in addition to
$prefix/lib/scsh/modules for compatibility with install-lib
** New implementation of open-pty
Instead of search for /dev/pty??, scsh now tries a wide variety of
ways to aquire a new pty and the corresponding tty.
** Bug fixes
argv[0] is now the first element of command-line
Fixes found by new test suite
Regexp for empty string
Argument checking for COPY-BYTES!
GC_PROTECTs for send_substring
format_date support for #f timezone
Added predicates for user-info and group-info
Reaping of stopped processes: Do not mark stopped processes as dead
md5-digest-for-port
| regexps return char-sets
standard-let in srfi-5
(%)read-delimited! checks for mutable buffer
leap second for srfi-19
The default image for the scshvm is now the installed scsh.image.
PKGLOCALEDIR and which install their locale files directly under
${PREFIX}/${PKGLOCALEDIR} and sort the PLIST file entries. From now
on, pkgsrc/mk/plist/plist-locale.awk will automatically handle
transforming the PLIST to refer to the correct locale directory.
RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).
branch.
Major changes between versions 4.2 and 4.3
------------------------------------------
- There is support for multibyte character sets in the line editor,
though not the main shell. See Multibyte Character Support in INSTALL.
- The shell can now run an installation function for a new user
(one with no .zshrc, .zshenv, .zprofile or .zlogin file) without any
additional setting up by the administrator.
- The manual now has a Roadmap section (manual page zshroadmap) to
give new users an indication of the most interesting parts of the manual.
- New option PROMPT_SP, on by default, to work around the problem that the
line editor can overwrite output with no newline at the end.
- New option HIST_SAVE_BY_COPY (on by default): history is saved by
copying and renaming instead of directly overwriting.
- New redirection syntax e.g. {myfd}>file opens a new file descriptor
and stores the number in $myfd, so that >&$myfd will work. Chosen not to
break existing code (and to be compatible with proposals for the Korn
shell).
- Substitutions of the form ${var:-"$@"}, ${var:+"$@"} and similar where
word-splitting is applied to the text after the :- or :+ (in particular,
where the SH_WORD_SPLIT option is in effect for compatibility) now behave
as in other Bourne- and POSIX-compatible shells when in the appropriate
emulation mode.
- New Posix-style zsh-specific tests [[:IDENT:]], [[:IFS:]],
[[:IFSSPACE:]], [[:WORD:]] test if character can appear in identifier, is
an IFS character, is an IFS whitespace character, or is considered as part
of a word (is alphanumeric or appears in $WORDCHARS). Note the pattern
code doesn't yet handle multibyte characters.
- The idiom =(<<<...) is optimised so that the shell internally turns
the ... into the contents of a file whose name is then substituted.
- Supplied functions catch and throw provide limited support for
exception handling using the `{ ... } always { ... }' syntax.
- Signals now accept the SIG as part of the name for compatibility with
other shells.
- Editor function argument-base allows non-decimal arguments for
editor widgets.
- As always, there are many enhancements to completion functions.
makeinfo if no native makeinfo executable exists. Honor TEXINFO_REQD
when determining whether the native makeinfo can be used.
* Remove USE_MAKEINFO and replace it with USE_TOOLS+=makeinfo.
* Get rid of all the "split" argument deduction for makeinfo since
the PLIST module already handles varying numbers of split info files
correctly.
NOTE: Platforms that have "makeinfo" in the base system should check
that the makeinfo entries of pkgsrc/mk/tools.${OPSYS}.mk are
correct.
developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
"extract" script for extraction. Many cases where a custom EXTRACT_CMD
simply copied the distfile into the work directory are no longer
needed. The extract script also hides differences between pax and
tar behind a common command-line interface, so we no longer need code
that's conditional on whether EXTRACT_USING is tar or pax.
Changes since last packaged version (2.3.0):
2.3.2
- fixed segfault due to checking the length of variables that I forgot to
remove from build_arg_vector() since the chroot root exploit fix in 2.3.0
2.3.1
- fixed stupid bug that caused rssh not to allow rsync and rdist
rather than PKG_FAIL_REASON, so that they provide useful error
messages in build logs, and so that they continue to work on platforms
where they aren't broken.
This is a terse description of the new features added to bash-3.1 since
the release of bash-3.0. As always, the manual page (doc/bash.1) is
the place to look for complete descriptions.
1. New Features in Bash
a. Bash now understands LC_TIME as a special variable so that time display
tracks the current locale.
b. BASH_ARGC, BASH_ARGV, BASH_SOURCE, and BASH_LINENO are no longer created
as `invisible' variables and may not be unset.
c. In POSIX mode, if `xpg_echo' option is enabled, the `echo' builtin doesn't
try to interpret any options at all, as POSIX requires.
d. The `bg' builtin now accepts multiple arguments, as POSIX seems to specify.
e. Fixed vi-mode word completion and glob expansion to perform tilde
expansion.
f. The `**' mathematic exponentiation operator is now right-associative.
g. The `ulimit' builtin has new options: -i (max number of pending signals),
-q (max size of POSIX message queues), and -x (max number of file locks).
h. A bare `%' once again expands to the current job when used as a job
specifier.
i. The `+=' assignment operator (append to the value of a string or array) is
now supported for assignment statements and arguments to builtin commands
that accept assignment statements.
j. BASH_COMMAND now preserves its value when a DEBUG trap is executed.
k. The `gnu_errfmt' option is enabled automatically if the shell is running
in an emacs terminal window.
l. New configuration option: --single-help-strings. Causes long help text
to be written as a single string; intended to ease translation.
m. The COMP_WORDBREAKS variable now causes the list of word break characters
to be emptied when the variable is unset.
n. An unquoted expansion of $* when $IFS is empty now causes the positional
parameters to be concatenated if the expansion doesn't undergo word
splitting.
o. Bash now inherits $_ from the environment if it appears there at startup.
p. New shell option: nocasematch. If non-zero, shell pattern matching ignores
case when used by `case' and `[[' commands.
q. The `printf' builtin takes a new option: -v var. That causes the output
to be placed into var instead of on stdout.
r. By default, the shell no longer reports processes dying from SIGPIPE.
s. Bash now sets the extern variable `environ' to the export environment it
creates, so C library functions that call getenv() (and can't use the
shell-provided replacement) get current values of environment variables.
t. A new configuration option, `--enable-strict-posix-default', which will
build bash to be POSIX conforming by default.
u. If compiled for strict POSIX conformance, LINES and COLUMNS may now
override the true terminal size.
2. New Features in Readline
a. The key sequence sent by the keypad `delete' key is now automatically
bound to delete-char.
b. A negative argument to menu-complete now cycles backward through the
completion list.
c. A new bindable readline variable: bind-tty-special-chars. If non-zero,
readline will bind the terminal special characters to their readline
equivalents when it's called (on by default).
d. New bindable command: vi-rubout. Saves deleted text for possible
reinsertion, as with any vi-mode `text modification' command; `X' is bound
to this in vi command mode.
e. A new external application-controllable variable that allows the LINES
and COLUMNS environment variables to set the window size regardless of
what the kernel returns: rl_prefer_env_winsize
Note that this is (mostly) a security fix release.
Changes since last packaged version (2.2.3):
2.3.0
- modified chroot_helper to parse the config file, to avoid arbitrary
chroot() (and thus root compromise)
- numerous documentation updates
- fix for va_start()/va_end()-related segfault on 64-bit architecture
- small bit of code cleanup
DEFAULT_PATH_VALUE as /usr/bin:/bin:${LOCALBASE}/bin:/usr/local/bin
(Instead of having non-existent default PATH directories.)
Bump PKGREVISION.
This is for PR 25044.
Okayed by bash2 maintainer.
